To all 1072/0771/ it may concern: 4

Be it known that I, WILLIAM H, BANFIL, a A

citizen of the United States, residing in Bosto n,

county of Suffolk, State of Massachusetts, 5 haveinvented an I mproveinentin Fire-Extinguishers, of which the following description, in connection with the accompanying drawings, is a specicatiomlike letters on the drawings representing like parts.

This invention relates to lire-extinguishers of that type containing acid and alkaline elements normally separated, but adapted to be brought in contact when the apparatus is turned bottom side up; and the invention has I5 for its object to improve the construction of a fire-extinguisher of this/type in several particulars-as, for instance, the cage containing the bottle is removably supported within the shell or case of the device to thereby facilitate zo the removal of the parts; also, the valve-plate,

which closes on a seat at the outlet of the bottle, is heldby a support which is attached to the bott-le, so as to be removed with the bottle; also, the valve-plate support is constructed toguide the valve-plate in its movements toward and from its seat and also limit the movement ofthe valve-plate awayfrom its seat; also, the valve-seat is formed at the extremity of atubular nipple, which is thrust 5o into the -outlet of the bottle and held therein by the frictionofa suitable'paeking, said nipple being connected tothe valve-plate support.

In accordance with this invention a cage adapted to contain ,any usual or suitable bottle or equivalentreceptacle is removably supported within the shell or case of theapparatus-as, for instance, it mayJrest uponin'- wardly-projectinglugs. The bottle has thrust y into its outlet a tubular nipple whichprojects 4o a short distance above the end of theoliottle and has formed at its upper extremity 'al valve-seat.' The valve-plate is made as adisk,

which is bodily movable toward andfrom its seat, anda support is provided for said 'valve'- plate which is constructed and arranged to not only support and. guide the valve-plata,"

but also limit its movement away from its seat. Means are provided for attaching the thecage;y YFigl'fl is a detail of a ring or collar having inwardly-projecting lugs on which the cage rests. Fig. 5 is a vertical section of the valve which controls the outlet of the bottle and which is attached to the end of the bottle.

The bodya of the extinguishenof any usual or suitable shape and size, has at its upper end a ring or collar l), which is externally screw-threaded and receives upon it va'cover c, which is also of anyusual or suitable construction. The ring or collar l) is formed or provided with a number of inwardly-projecting lugs b', (see Fig. 4,)fupon which a cage rests, which contains the bottle containing the acid element.

d representsa ring which forms a coperative part of the cage, and said ring is made of suitable shape and size to rest upon the lugs b of the ring or collar b. Upright rods or bars ddepend from the ring d, whichiform the sides of the cage, and said rods or bars are connected at their lower ends to a ring d2, and midway the length of said rods or bars a ring d3 is preferably provided. The cage thus `described merely rests upon the lugs b', and consequently is removable.

e represents the bottle or other receptacle adapted to contain the acid element, and said bottle is containedtin the cage and is supported upon the ring d2. The bottle will be made of any required size and shape. At the outlet of the bottle a valve is provided for controlling it, which is adapted to yclose the outlet by gravity and to open by gravity when the extinguisher is turned bottom side up, and the valve herein shown is att-ached to the ,end of the bottle, so as to be removed with the bottle whenever desired.

frepresents a tubular nipple which is thrust into the outlet of the bottle and which is held therein by the friction of a suitablefpacking f, applied to the exterior thereof, andsaid Vvalve-seat.

v The nipplefis formed integral with or attached to a plate f3, which when the nipple is thrust into the bottle rests upon or against the end thereof. A number of short rods f4 project upward from the plate f3, which support at their upper ends a plate f5 in a plane in parallelism with the plate f3. The valveplate f6 is made as a disk and is provided IOO with a number of holes which receive the rods f4, and said plate normally rests by gravity on the valve-seat f2, yet is free to slide on the rods f4 as guides when the extinguisher is turned bottom side up. The plate f5 limits the movement of the valve -plate f6 away from its seat, and being held in a xed position relative to the valve-seat it will be seen that the valve-plate will always move away from its seat a predetermined distance. This is important, as the outlet of the bottle for the escape of the contents will always be the same. The plate f 3, rods f4, and plate f5serve as and constitute a support for the valve-plate f and also guides the movement of said valveplate and also limits its movement away from its seat.

The valve-plate support is designed to be attached to the bottle, and as a simple way of accomplishing this result a spring-acting engaging device is provided, which, as herein shown, consists of a number of integrallyformed spring-acting fingers g, made as a ring to spring onto the end of the bottle, said ring being attached to the plate f3.

It is obvious that other lneans may be provided in lieu of the spring-acting engaging device herein shown for attaching vthc valve to the bottle.

The means herein shown for limiting the movement of the valve-plate away from its seat is simple; yet I do not desire tolimit my invention to the particular means herein shown for accomplishing this result.

In other fire-extinguishers of this type, so far as I am aware, the means employed for limiting the movement of the valve -plate away from its seat is variable, usually depending upon the height of the bottle; but herein the means employed is of a predetermined or fixed character, and consequently the valve-plate always moves a predetermined distance away from its seat.

I claim- 1. In a fire-extinguisher, a shellor case having a cover and containing a cage, combined with a bottle supported by said cage provided at its outletwith a valve-seat, a valve-plate freely movable toward and from its seat, and a support for said valve-plate attached to the neck or end ot said bottle,'substantially as described.

2. In a tire-extinguisher, a shell or case having a cover and containing a cage, combined with a bottlesupported by said cage, a tubular nipple thrust into the outlet of said bottle formed or provided at its extremity with a valve-seat, and supported by a platef, resting on the bottle, a disk movable toward and from said seat and means attached to said plate for supporting and guiding said disk, and means for attaching said plate to the bottle, substantially as described.

. 3. In ahrc-extinguisher,ashell or case having a cover and containing a cage, combined with abottle supported by said cage provided at its outlet with a valve-seat, a valve-plate therefor, and a valve-plate support attached to said bottle having guides for supporting and guiding said valve-plate, substantially as described.

4. In ahrc-extinguisher, a shell crease having a cover and containing a cage, combined with a bottle supported by said cage provided at its outlet with a valve-seat, a valve-plate therefor, and a valve-plate support attached to said bottle having guides on which-said valve-plate slides, substantially as described.

5. In a lire-extinguisher, a shell or case having a cover and containing a cage, combined With a bottle supported by said cage provided at its outlet with a valve-seat, a valve-plate therefor, and a valve-plate'support attached to said bottle having means for limiting the movement of the valve-plate away from its seat, substantially as described.

G. In a fire-extinguisher, a shell or case having a cover and containing a cage, combined with a bottle supported by said cage provided at its outlet with a valve-seat, a valve-plate movable toward and from said seat, and a valve-plate support having a spring-acting engaging device engaging the end of the bottle, substantially as described. 7. In aine-extinguisher, ashell orcase having a cover and-containing a cage, combined with a bottle supported by said cage provided at its outlet with a valve-seat, a valve-plate freely movable toward and from its seat, and a support for said valve-plate removably attached to the end of thebottle, substantially as described.

S. In a fire-extinguisher, a shell or case hav- ICO ing a cover and containing a cede, combined IIO with a bottle supported by said cage, atubular nipple thrust into the outletof s aid bottle formed or provided at its extremity with a valve-seat, and formed integral with a plate f3 which restson the end of the bottle, a disk movable toward and from said seat, guiderods projecting from said plate which guide said disk and a stop supported by said rods for limiting the movement of said disk away from its seat, and a plurality of spring-aeting fingers on said plate which slip over the lip on the vend of the bottle, substantially as described.

In testimony whereof I have signed my name to this specification in the presence, of two subscribing witnesses.`
